Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a crushing vacuum feeding device. Background Art

[0002] Vacuum feeding is a commonly used means in the powder conveying process. However, due to the frequent occurrence of pseudo agglomeration in powders, the diameter of the vacuum feeding pipe for vacuum packaging is usually relatively small. During the conveying process of such agglomerated materials, it is easy to block the feeding pipe and affect the conveying efficiency. In the prior art, the common solution is to crush and disperse the agglomerated materials before vacuum conveying, such as the technical solutions described in patents with application numbers CN201820806038.1, CN202321216357.4, etc.

[0003] During the production process of powdered materials such as rice protein, it usually does not get damp and form true agglomerates. The generated pseudo agglomerates do not affect the raw material quality and normal use, and the pseudo agglomeration phenomenon during the production process of powdered materials such as rice protein is not serious. In order to avoid blockage during vacuum feeding, it is necessary to crush such pseudo agglomerates. However, such pseudo agglomerates require relatively little crushing force. Setting up a separate crushing link has high energy consumption and is not convenient to operate. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the utility model provides a crushing vacuum feeding device used in the production process of powdered materials such as rice protein, which can disperse agglomerated materials without additionally setting up a crushing device.

[0027] This embodiment provides a crushing vacuum feeding device, including a mounting platform 1, a fixed seat 4, a rotating shaft 8, a rotating cylinder 9 and a sealing sleeve 12;

[0028] As Figures 1-4 shown, a first drive motor 2 and a second drive motor 3 are arranged on the upper part of the mounting platform 1, and the first drive motor 2 and the second drive motor 3 provide power for the transmission components;

[0029] The fixed seat 4 is arranged at the lower part of the mounting platform 1, the first output shaft 5 of the first drive motor 2 extends into the fixed seat 4, a connecting sleeve 6 is arranged at the lower part of the fixed seat 4, a vacuum feed pipe 7 is arranged at the lower end of the connecting sleeve 6, the fixed seat 4 provides installation support for the connecting sleeve 6, the upper end of the vacuum feed pipe 7 is connected to a vacuum feeding device, and the materials at the lower end of the vacuum feed pipe 7 can be sucked to the upper end of the vacuum feed pipe 7;

[0030] One end of the rotating shaft 8 is connected to the first output shaft 5, and the other end of the rotating shaft 8 passes through the connecting sleeve 6 and extends into the vacuum feed pipe 7. When the first output shaft 5 rotates, it drives the rotating shaft 8 to rotate;

[0031] A spiral feeding blade 9 is arranged at the end of the rotating shaft 8 in the vacuum feed pipe 7. When the rotating shaft 8 rotates, the spiral feeding blade 9 can lift the materials at the lower end of the vacuum feed pipe 7 to a certain height;

[0032] Both ends of the rotating cylinder 10 are sleeved on the outer side of the rotating shaft 8 by using sliding bearings 11, and the rotating cylinder 10 can rotate relative to the rotating shaft 8;

[0033] The upper end of the rotating shaft 8 is connected to the second output shaft 23 of the second drive motor 3 by belt drive. When the second output shaft 23 rotates, it drives the rotating cylinder 10 to rotate;

[0034] At the lower end of the rotary drum 10, there are crushing blades 12. When the crushing blades 12 rotate, they can crush the materials lifted by the spiral feeding blade 9, facilitating the suction of materials by the vacuum feeding equipment.

[0035] The sealing sleeve 13 is arranged at the intersection of the connecting sleeve 6 and the vacuum feed pipe 7. The sealing sleeve 13 is sleeved outside the connecting sleeve 6 and is hermetically connected to the vacuum feed pipe 7 by welding. The sealing sleeve 13 keeps the vacuum feed pipe 7 in a sealed state, preventing air leakage from affecting the vacuum feeding operation.

[0036] Furthermore, a first bearing 14 is arranged in the fixed seat 4. The first output shaft 5 can cooperate with the first bearing 14, and the first bearing 14 facilitates the rotation of the first output shaft 5.

[0037] Furthermore, a driven wheel 15 is arranged at the upper end of the rotary drum 10, and a driving wheel 16 is arranged on the second output shaft 23. The driving wheel 16 and the driven wheel 15 are connected by a transmission belt 17. The second output shaft 23 can drive the rotary drum 10 to rotate through the transmission belt 17.

[0038] Furthermore, an installation seat 18 is arranged at the lower part of the installation platform 1. A second bearing 19 that can cooperate with the second output shaft 23 is arranged in the installation seat 18, and the second bearing 19 facilitates the rotation of the second output shaft 23.

[0039] Furthermore, a graphene cushion block 20 is arranged between the lower end of the rotary drum 10 and the rotating shaft 8.

[0040] Furthermore, a lateral opening 21 that can cooperate with the conveyor belt 17 is arranged at the upper end of the connecting sleeve 6. The lateral opening 21 ensures that the conveyor belt 17 does not interfere with the connecting sleeve 6 during the movement process.

[0041] Furthermore, the crushing blades 12 are located 10 - 40 mm above the spiral feeding blade 9. The smaller the distance between the crushing blades 12 and the spiral feeding blade 9, the more convenient it is to disperse the block-shaped materials.

[0042] Furthermore, a positioning ring plate 22 is arranged on the outer side of the middle part of the connecting sleeve 6. The positioning ring plate 22 facilitates the limit fixation of the upper end of the sealing sleeve 13.

[0043] Working principle: When the present utility model is in use, the upper end of the vacuum feed pipe 7 is connected to a vacuum feeding device, and the materials move upward under the suction of the vacuum feeding device. Some agglomerated materials cannot be sucked away.

[0044] After the first drive motor 2 and the second drive motor 3 are powered on, the rotating shaft 8 and the rotating drum 10 drive the spiral feeding blade 9 and the crushing blade 12 to rotate respectively. The spiral feeding blade 9 lifts the agglomerated materials to the crushing blade 12, and the crushing blade 12 breaks up the agglomerated materials. Then the materials are sucked away by the vacuum feeding device;

[0045] The first drive motor 2 and the second drive motor 3 are respectively connected to the spiral feeding blade 9 and the crushing blade 12 through the rotating shaft 8 and the rotating drum 10, and can provide different rotation speeds for the spiral feeding blade 9 and the crushing blade 12 to avoid the situation where the agglomerated materials rotate synchronously with the crushing blade 12; By arranging the sealing sleeve 13 at the intersection of the connecting sleeve 6 and the vacuum feed pipe 7, the vacuum feed pipe 7 maintains a sealed effect; The graphene cushion block 20 makes the rotating drum 10 and the rotating shaft 8 have a sealed effect, preventing the powder from entering between the rotating shaft 8 and the rotating drum 10 and jamming the two.

[0046] It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present invention, and the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
